IMPROVEMENT IN DOQR-SECURERS.

Specification forming part of Letters Patent No. 208,176, datedSeptember 17, 1878 application filed July 15, 1878. i

To all whom it may concern:

Be it known that '1, WILLIAM ALLEN IN- GALLS, of Providence, in thecounty of Providence and State of Rhode Island, have invented certainImprovements in Door-Fastpnings, of which the following is aspecificaion:

This invention relates to that class of removable or portabledoor-fastenings adapted to be carried in the pocket when not. in use, inwhich a shank is employed which is adapted to be engaged with the jambof the door, so as to lie partially between the jamb and the edge of theclosed door "with a part projecting, and supports on its projecting partadjustable devices, whereby the door may be fastened.

The invention has for its object to provide certain improvements in theconstruction of the shank and the adjustable devices, whereby a moreconvenient fastening is produced than heretofore.

To this end the invention consists in the improvements which I will nowproceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a top view of my improved fastening, showing itsposit-ion in use, the door'and jamb being shown in section. Fig. 2represents a similar view, showing the fastening adjusted to leave thedoor free. Fig. 3 represents a sectional view of the fastening in theposition shown in Fig. 2. Fig. 4 represents a perspective view of thefastening in its operative position. Fig. 5 represents an end view ofthe button.

Similar letters of reference refer to like parts in all the figures.

In the drawings, arepresents the shank of my improved door-fastening.-This shank is flattened at one end, where it lies between the door and jamb when in use, and its other endis cylindrical and provided with ascrew-thread. Between the flattened and threaded ends of the shank thesides thereof are inclined, as shown in Fig. 3, so as'to give thecentral portion, 0, of the shank a partial wedge shape horizontally, butnot vertically, the upper and lower edges of the shank being parallelalong the portion 0. The flat end of the shank is pro vided with alateral flange, d, to engage with a mortise or orifice in the jamb j ofthe door in the usual manner. The threaded end of the shank is providedwith a nut, e. v

f represents a button, which is located on the shank a between theflange d and nut c. This button is adapted to revolve loosely on theshank, and is provided with an orifice, g, through which the shankpasses. The orifice g is located as close as possible to one edge of thebutton, as shown in Fig. 5, so that the button is pivoted eccentricallyto the shank.

The form of the face of the button is preferably as represented in Fig.5, the edge f nearest the orifice being curved, and extending equally inboth directions from said orifice,

while the other edges, in connection with said curved edge, form twowings, i, of equal size and weight. This construction of the buttonenables it to automatically assume the position shown in Fig. 5, withits major axis or length extending horizontally. r

The fastener is operated by placing the thin end of the shank againstthe jamb of the door before the door is closed, with the flange dprojecting into a mortise in the jamb, the

wedge-shaped portion 0 and the threaded end of the shank projectingbeyond the jamb, and the button resting on the portion 0. The button isthen turned, as shown in Fig. 2 and in dotted lines in Fig. 5, so thatthe edge f of the button will be contiguous to the door 70.

When in this position the door can readily.

swing by or past the button, the wedge-shaped portion a enabling thebutton'to tilt horizontally, as shown in Fig. 2, so that the edge f willlie close to the side of the shank and be out of the way of the door, oryield to the latand swings automatically into position shown a in Figs..1, 4, and 5, after which the nut is turned to force the buttoninwardly, its wings t i projecting on each side of the shank and bearingequally upon the door and the jamb, as shown in Fig. 1. This uniformbearing of the nut on both sides of the shank braces the nut andprevents it from being broken readily by pressure against the outside ofthe door, as will be readily seen. The outer end of the nut is preferabyprovided with a whistle, w, of any suitable construction, so that thefastener is adapted to serve also as an alarm.

The device described constitutes a very sccure, compact, and simplefastening, and its whistle attachment makes its additionally convenientand useful.

I am aware that a door-fastener has been,

'both directions from the shank and bear on both the door and jamb, itcannot automatically assume a horizontal position on account of itssectional construction, its wings having to be held in position untilthe nut is turned to hold them in place by pressing them against thedoor and jamb. My button f, however, is made in a single piece, and isadapted, as be; fore described, to assume its operative positionautomatically or bygravitation.

I claim as my invention- The button f, made in one piece, having theorifice g, and adapted to assume its operative position by gravitation,in combination with the flanged and threaded shank a, having the nut e,as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribin g witnesses.

WILLIAM ALLEh 'INGALLS.
